It worth understanding the difference between the two types of amplification: a passive soundbar does not have its own amplifier and receives amplification from the signal source, while an active soundbar has a built-in amplifier. The same active type of amplification is used in the YAS-109 and the SIGNA S2.

There are stereo soundbars and multichannel ones. It is with the help of multichannel devices that you can get volumetric sound. The number of channels in the considered devices is the same - 2.1.

Subwoofers

Soundbars can have a built-in or external subwoofer. The first type is inseparable from the soundbar body, but for the second, you can choose a good location for deep bass. A built-in subwoofer is only present in the YAS-109. The SIGNA S2 comes with an external subwoofer. Yamaha YAS-109 has the ability to handle wired connections from an external subwoofer, while Polk Audio SIGNA S2 only has wireless connections.

Multichannel surround

Unlike stereo, when reproducing multichannel sound, each specific direction of sound corresponds to its dedicated channel with a separate independent loudspeaker, which creates a three-dimensional sound stage. The YAS-109 received rating 8 out of 10 for multichannel audio processing, but the SIGNA S2, in the same category, earned 4 out of 10 points.

The peculiarity of Dolby Atmos is that this format is object-oriented, that is, each object of the audio signal is sounded separately and linked to its spatial location. If we look at the models in terms of Dolby Atmos support, then none of these soundbars can work with this technology.

DTS:X is an algorithm for processing sound scenes by the processor, linking directly to objects, rather than channels, and calculating the optimal distribution of sound output in a room. This ability to reproduce surround sound with DTS:X technology is not implemented in any of the soundbars in this comparison.

The presence of Wi-Fi in the soundbar allows you to get rid of wires when connected to a sound source and get minimal audio latency when playing content from streaming services. Wireless connection via Wi-Fi is possible on the YAS-109.

Bluetooth connection is now one of the main communication protocols for speaker systems, which provides excellent quality and minimal audio latency. The availability of Bluetooth protocol, we can see in both models. The YAS-109 has 1/1 HDMI inputs/outputs, but the SIGNA S2 got 1/0 HDMI inputs/outputs from the manufacturer.

HDMI ARC is a very usefull technology that creates a two-way communication channel between a TV and another device. This is convenient since there is no need to use optical and other cables in the system. HDMI ARC is basic for both soundbars.
